Hi @nerull1976
The best way to find a problem is to simplify the area where the error occurs.
For example: Simplify , sketch that saves the data and then fetches the data and compares it with the saved ones.
Afterwards, make a sketch that only fetches the data saved in the previous sketch and prints them on the serial monitor and see if they are correct.
If not, it works ok, do the same test using RemoteXY,
and see if it works correctly.
And so, expand the testing area.
